A data-driven design framework for early stage PSS design exploration

14th February 2020
No Comment

Abstract Ubiquitous and pervasive computing holds great potential in the domain of Product-Service Systems to introduce a model-driven paradigm for decision support. Data-driven design is often discussed as a critical enabler for developing simulation models that comprehensively explore the PSS design space for complex systems, linking of performances to customer and provider value. Emerging from […]

Robust Optimization Scheme for Inverse Method for Crystal Plasticity Model Parametrization

6th February 2020
No Comment

Abstract A bottom-up material modeling based on a nonlocal crystal plasticity model requires information of a large set of physical and phenomenological parameters. Because of the many material parameters, it is inherently difficult to determine the nonlocal crystal plasticity parameters. Therefore, a robust method is proposed to parameterize the nonlocal crystal plasticity model of a […]

Peeling of metal foil from a compliant substrate

9th January 2020
No Comment

Abstract Large displacement peel was studied for cases where a compliant substrate leads to a large value of the root rotation. An existing simplified beam model to calculate the peel fracture energy was modified to allow for a kinematic hardening beam model of the foil. The steady-state peel force and the root rotation were used […]

Trouser tear testing of thin anisotropic polymer films and laminates

18th December 2019
No Comment

Abstract This research has investigated the essential work of fracture (EWF) from trouser tear test of polyethylene terephthalate (PET), low-density polyethylene (LDPE) films and their corresponding laminate using a convenient cyclic tear test method. Propagation of tear crack in these thermoplastics deflects from the initial crack path due to the material anisotropy. An improvement to […]

Simulation-driven design, Projects 2018

11th January 2019
1 Comment

Modelling and simulation are today a natural part of engineering design in businesses of all types and sizes. However, transition from simulation as primary a tool for verifying solutions that are already decided upon towards the use of simulation to stimulate creation of new concepts and provide guidance towards more optimized designs, especially in early […]
